The Schedule referred` to in these Letters Patent and making part cf the same4 To all whom it mag/concern:

Be it known that I, FRANKLIN H. MORRILL, of

Philadelphia, in the county of Philadelphia, and State `to the bobbins at the saine speed when it is traversing from the small onto the large part of the cone thereof.

To accomplish this, I. use a lieart-shaped gear, applied to a swingingarxn, and located between two pinions, by one of which it isdriven, and tothe other of which it imparts a variable4 rotary motion.

Figure 1 is an end elevation of a bobbinframe, with my improvement applied.

Figure 2 is a plan View of same.

Figure 3 is a detached view of the heartshaped gear and portion of the traverse-motion.`

To enable those skilled in the art to-make and use my invention, I will now proceed to describe its construction and operation. y,

The ends Fand F' of the framing are made of any suitable material, and in the form as shown in iig. 1.

.SaidV ends are connected together by means of the Secured at the centre, and" on the inner side of the ends lll-aud l1", are two uprights, V--and V', which are braced'by means of` pieces I and P.

` Underneath, and secured to the piece P', are jointed arms, having pivoted on their ends skein-drums S D.

Between` the rails R1 and R2, and at a proper distance apart, are two bearing-rails, 1t* and R5.

Placed upon 'said rails, zuul'directly on a line with the skein-drums S D and SD', are one or `more spindles, S, on which are secured Vpulleys p, over. which are passed belts or cords C.

On either end of the spindles S, are placed bobbins B, of ordinary construction. y

The ends of said bobbins rest in guides or supports g, secured to the side of the rails R1 or R2.

Working in bearings secured in the centre, and at the lower partof the framing, is a shaft, E, to which is secured a driving-cylinder, D 0,which communicatesmotion to the spindles S, by means of the belt or cord C'.

On the end F of the framing, and suspended from the top and centre of the same, by means of the vibrating arm A, is a heart-shalied gear, H G.

On the opposite sides of thev said gear, and secured in the-framing, are two studs, l and T, on which work pinious N and N, having proj ecting tubes formed on one side of them, which encircle and revolve on the studs.

The tube on the stud T is provided with fast and loose pulleys Y and Y.

The tube on the stud T is also provided with a pulley, YZ, a twisted belt, L, passing over it and around a pulley, Y, secured to the end of the shaft E of the driving-cylinder D C. y

On the stud T, and on'one side of the pinion N, is placed a small pinion, N2, which gears with the spurwheel S W, the said Wheel being secured to the end of the shaft D, which works in bearings in the ends F and F of the framing, and runs parallel to and imme# diately below the rail R1.

0n the inner side of the ends F and F, are placed two traversing-bars, T R and 'l R', the said bars hav.- ing a rectangular slot formed near each of their ends, through one of which the shaft D passes, andthe opposite ends work on pins, secured tothe inner side of the framing.

On each side of the openings through which the shaft D passes, are secured projecting pins e and e', between which work the heart-shaped cams M and M', said cams being secured to vthe shaft D.

A short distance above the upper edge of the bars T R and 'l R', and secured to them bymeans of rods, is a traversing-rail, 1 B, having secured on its upper edge, and alongside of each bobbin, ra guide, d.

l Operation. `Motion is given to the pulley Y1, which turns the heart-shaped gear H G, through the pinion N1.

. H G, and the vcanis M and M will assume the pos'itiony as shown iniig. 3. V

When the point a of the-gear HG has reached the pinion Nl, the leverage heilig greater, and less between the pinion N and vthe Vpoint l) of the gear, the speed of the pinion Nwill be less; and as the yarn is now passing on to the cone-part of the bobbin, and having a larger circumference to travel, the speed inus't necessarily be slower.

It will be obviousy from the above method of regulating the speed of the bobbins, that the yarn will be wound upon them in a. regular manner, consequently the liability of the yarn twisting and breaking will be prevented.

Having thus described my invention, its construction, and. operation,

VVhztt I claim, and desire to secure by Letters Petent of the United Statesfis- The arrangement of the heart-shaped gear H G,

arm A, and pinions N and N, for the purpose of giving :t variable rotary motion to the bobbns B, substantially in themanner and for the purpose specified. In testimony whereof, I have hereunto signed my naine, in the presence of two subscribing witnesses.

v FRANKLIN H. MORRILL.
